The Rebels captain will be reassessed later this week after the shoulder has been allowed to settle, and has returned to Brisbane in the interim.

Both Timani and Higginbotham were replaced in the preliminary Wallabies squad, with their places being taken by Waratahs lock Kane Douglas and Western Force backrower Ben McCalman respectively.

The Wallabies are in camp in Sydney preparing for the start of the Lions Tour Test series, which opens at Suncorp Stadium in Brisbane on June 22.

The current squad of 25 will be enlarged to 31, with the final six players to be added on June 11, after Super Rugby has entered its June break.

Scrumhalf Nic White, who will play for the Brumbies against the Melbourne Rebels in Canberra on Friday night, will join the Wallabies camp for training tomorrow during his Super Rugby team's training free day.

Melbourne Rebels fullback Kurtley Beale is also training with the squad this week.
